In respect to this, what is the proper gap between deck boards?

The goal is to have about an 1/8-inch gap (the diameter of an 8d nail) between boards after the decking has dried to its equilibrium moisture content. If the decking is installed wet, as is often the case for pressure treated material, it is best to install the boards tight, letting gaps form as the wood dries.

Additionally, how do I make sure deck boards are square? Measure the distance from one corner of the ledger board (the rim joist attached to the house) to the opposite corner on the outside of the deck. Then, measure the distance between the opposite two corners. If the two measurements are equal, the deck is square.

Consequently, can you use 2x6 for deck boards?

Wood decking is commonly available in 2x6 and 5/4 x 6 profiles. 5/4 x 6 is produced specifically for decking and is milled with a radius edge or bull nose. 2x6 is thicker and is stronger, but is also more expensive. Spacing between deck boards provide a few critical functions.

Do you pre drill decking boards?

Pre-drilling is not just about wood-splitting. It fundamentally changes the nature of the joint. Take the example of screwing decking to joists. If you were to pre-drill the deck board so the hole was WIDER than the screw but the screw is allowed to bite into the joist.

What length deck screws should I use?

Most decking screws are 8-gauge and, while 2 1/2 inches is the minimum length needed to hold decking boards to the joists, 3-inch screws are commonly used to provide extra holding power against the upward pressure of shrinking or warping boards. Specialty decking materials have different requirements.

Should deck boards be parallel or perpendicular to House?

Well, normally girders are parallel to the house, the joists are perpendicular and the deck boards are parallel. This is because the ledger acts as the a girder against the house supporting the joists. If you run the deck boards perpendicular to the house, then the joists need to be parallel.

How do I keep my deck boards straight?

Should you use nails or screws for a deck?

Screws are a "superior" fastener over a nail (they have far superior tensile strength)—especially if you're talking about screwing down decking. Using your deck example—you should use nails to attach the joists to the deck framing but use screws to fasten down the decking itself.

Do I need to drill pilot holes for deck screws?

First, drill a pilot hole through both boards. Pilot holes guarantee that your screw won't break off and your wood won't crack. For most hardwoods, the pilot hole should be at least as large as the screw's minor diameter. If the screw has deep threads, or the wood is very hard, the pilot hole should be another 1/64-in.

Should decking boards be horizontal or vertical?

In what direction should decking boards be placed (horizontal / vertical) compared to the deck? The boards are usually placed horizontally perpendicular to the adjacent wall. This choice is above all aesthetic, but it also important to be sure that the direction of the boards does not hinder water drainage.

Are 2x6 strong enough for deck joists?

2x6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. Most decking is not strong enough to support longer spans than 16". Some builders reduce joist spacing to 12" on center to strengthen the deck frame or to increase maximum allowable joist spans.
